Examination of Functional Capacity, Pulmonary Functions, Pain, Depression, Sleep and Quality of Life in Young Adults After COVID-19: A Descriptive Observational Study

Abstract

Aim: This study aims to reveal whether COVID-19 affects functional capacity, pulmonary functions, pain, depression, sleep, and quality of life in healthy young adults. Methods: The present study was conducted with 52 participants consisting of post-COVID-19 pneumonia (n=26) and healthy adults (n=26). Outcome measurements included the 6-minute walk test, spirometry (FEV1, FVC, FEV1/FVC, MVV), the visual analog scale, algometer, and hand-held dynamometer as well as questionnaires including Beck depression inventory, Pittsburgh sleep quality index, Short Form-36, International Physical Activity Questionnaire, Fatigue severity scale, and Corbin posture scale. Results: According to the comparisons between the groups, there were no statistically significant differences in functional capacity (p=0.350), pulmonary function parameters including FEV1, FVC, FEV1/FVC and MVV (p=0.660; p=0.226; p=0.589; p=0.511 respectively), pain intensity (p=0.467) and pressure pain threshold at three different points (upper part of m. trapezius, m. tibialis anterior, and mm. interossei dorsales of the hand) (p=0.305; p=1.000; p=0.103 respectively), depression (p=0.119), sleep quality (p=0.267), subdomains of quality of life (p=0.873; p=0.056; p=0.308; p=0.632; p=0.251; p=0.290; p=0.560; p=0.671), upper extremity, lower extremity, and grip strength (p=0.097; p=0.228; p=0.117 respectively), fatigue (p=0.873), and posture (p=0.933) between the infected and the non-infected group. Most participants in both the infected and the non-infected groups were sufficiently active (38.5% and 46.2%, respectively; p=0.481). Conclusion: There were no significant differences in physical, mental, or social health between groups when comparing post-COVID-19 pneumonia with mild functional limitation to healthy young adults. The current study suggests that there are no long-term effects of COVID-19 on this cohort.
